| 中文摘要: |
| 河南省镇平县楸树湾矿区外围位于秦岭造山带北秦岭褶皱带东段,是一处斑岩型铜钼矿床。研究显示,矿床的形成与燕山期(约147 Ma)楸树湾复式花岗闪长斑岩体密切相关,成矿作用受控于以岩体为中心的环带状蚀变系统及层间-裂隙构造。矿体主要呈层状、似层状赋存于古元古界秦岭岩群雁岭沟岩组的黑云石英片岩及接触交代矽卡岩中。矿石具典型细脉-浸染状构造,金属矿物以辉钼矿、黄铜矿、黄铁矿为主。区域与矿区地质、地球物理、地球化学特征指示,深部及外围仍具较大找矿潜力,是深化秦岭东段斑岩成矿系统研究与勘查的重要窗口。 |
| 英文摘要: |
| The periphery of the Qiushuwan mining area in Zhenping County, Henan Province is located in the eastern part of the North Qinling fold belt of the Qinling orogenic belt. It is a porphyry copper-molybdenum deposit. The study reveals that the formation of the deposit is closely related to the Yanshanian (ca. 147 Ma) Qiushuwan composite granodiorite porphyry, and the mineralization is controlled by the ring-shaped alteration system and interlayer-fracture structure centered on the rock mass. The ore bodies are mainly layered and stratoid in the biotite quartz schist and contact metasomatic skarn of the Yanlinggou Formation of the Paleoproterozoic Qinling Group. The ore has a typical veinlet-disseminated structure, and the metal minerals are mainly molybdenite, chalcopyrite and pyrite. The geological, geophysical and geochemical characteristics of the region and the mining area indicate that the deep and peripheral areas still have great prospecting potential, which is an important window to deepen the research and exploration of the porphyry metallogenic system in the eastern Qinling Mountains. |
